[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a sliding door device, and more particularly, to a braking device for braking movement of a sliding door body and a sliding door device provided with a driving device for moving the sliding door body.
[0002]
[Background]
As a partitioning means for partitioning a plurality of adjacent building spaces such as a corridor and a room in a building so as to be openable and closable, an overhanging sliding door device is known. In this upper suspension type sliding door device, a guide rail as a guide member is disposed above the sliding door body, and a plurality of rollers are arranged and engaged with the guide rail in the moving direction of the sliding door body, and the sliding door body is engaged with these rollers. The sliding door main body is guided by the guide rail and moved by the rolling of the roller.
[0003]
The upper suspension type sliding door device includes a braking device for reducing the moving speed of the sliding door body when the sliding door body approaches the closing limit position, and a drive for automatically moving the sliding door body to the closing limit position. Some are equipped with devices.
[0004]
[Problems to be solved by the invention]
On the other hand, because the demand for the suspension type sliding door device is currently increasing, the members and devices placed above the sliding door body are downsized so that the sliding door device can be used in various buildings and various applications. There is a demand for a compact structure. In order to meet such a demand, the roller engaging with the guide rail must have a smaller diameter than before.
[0005]
In this way, if the roller has a smaller diameter than the conventional one, the distance from the engaging portion of the roller with the guide rail to the central portion of the roller is shortened, so that the rolling resistance when the roller rolls along the guide rail is reduced. Will increase. The above-described braking device and driving device are attached to the suspension type sliding door device provided with such a roller having a large rolling resistance, and the braking force of the braking device acts on the moving sliding door body, or the driving device moves to the sliding door body. When a force is applied, depending on the positional relationship between the moving axis of the sliding door body and the braking axis of the braking device, or the positional relationship between the moving axis of the sliding door body and the driving axis of the driving device, the roller rolling may occur. There is a possibility that smooth movement of the sliding door body cannot be secured due to resistance.
[0006]
In addition, in a hanging type sliding door device in which the diameter of the roller is the same as the conventional one, the positional relationship between the moving axis of the sliding door body and the braking axis of the braking device, the moving axis of the sliding door body, and the driving axis of the driving device It is important to appropriately set the positional relationship so that the smooth movement of the sliding door body can be ensured.
[0007]
An object of the present invention is to provide a sliding door device that can ensure a smooth movement of the sliding door main body even if a braking device and a driving device are provided.
[0008]
[Means for Solving the Problems]
The sliding door device according to the present invention includes a sliding door main body, a guide member that guides the movement of the sliding door main body, and a braking device for braking the movement of the sliding door main body, and is guided by the guide member. The position of the moving axis of the sliding door body and the position of the braking axis of the braking device that applies a braking force to the sliding door body are the same or substantially the same position in the thickness direction of the sliding door body. It is what.
[0009]
According to this sliding door device, the position of the moving axis of the sliding door main body guided by the guide member and the position of the braking axis of the braking device that applies a braking force to the sliding door main body coincide or substantially coincide with each other in the thickness direction of the sliding door main body. Therefore, even if the braking force of the braking device acts on the moving sliding door body, this braking force can eliminate or reduce the force to move the sliding door body in the sliding door body thickness direction. Therefore, a large frictional force that acts as a resistance force for the movement of the sliding door body does not occur, and a braking force having the same or substantially the same magnitude as the original braking force of the braking device can be applied to the sliding door body. The sliding door body can be moved while being smoothly braked as specified.
[0010]
The braking device in this sliding door device may operate when the sliding door body moves to the closing limit position, may operate when the sliding door body moves to the opening limit position, and both of them. But you can.
[0011]
The type and structure of the braking device are arbitrary. For example, the piston rod is connected to or abutted with one of the sliding door body and the stationary member, and attached to the other, and the end of the piston rod is slidable. It may be a fluid pressure type braking device using a gas such as air or a liquid such as oil or water, or a fluid pressure braking device constituted by a cylinder device having a cylinder body inserted into the cylinder body, or attached to one of the sliding door body and the stationary member A fluid agitation braking device may be provided that includes a rack member and a pinion that is disposed on the other side and rotatably meshed with the rack member, and fluid such as oil is agitated by rotation of the rotation center shaft of the pinion. Further, the braking device is arranged at the front or rear in the closing direction of the sliding door main body, or both, and elastic members such as springs, rubber, soft resin, etc., which elastically receive the moving sliding door main body. The elastic braking device formed by the above may be used, and this elastic member may be attached to the sliding door body. .
[0012]
When the brake device is a fluid pressure brake device, the brake axis is a moving axis of the piston rod with respect to the cylinder body. Further, when the braking device is a fluid agitation type braking device, the braking axis moves with respect to the moving axis of the pinion that moves while rotating with respect to the stationary rack member, or the pinion that does not move when only rotating. This is the axis of movement of the rack member to be performed. When the braking device is an elastic braking device, the braking axis is an elastic axis of an elastic member that is elastically deformed.
[0013]
The sliding door device provided with such a braking device may or may not be provided with a drive device for automatically moving the sliding door main body to the closing limit side or the opening limit side or both. Also good. Further, the drive device is not a special device, and uses a guide member that is fixedly inclined downward to the closing limit side, for example, or a direction of downward inclination according to the moving direction of the sliding door main body. It is also possible to use a guide member in which the sliding door body is moved by the weight of the sliding door body.
[0014]
Further, the sliding door device provided with the above braking device may be one in which the guide member for guiding the sliding door main body is disposed above the sliding door main body, or may be disposed below the sliding door main body. It may be arranged.
[0015]
Further, the sliding door main body may be provided with a plurality of rollers arranged in the moving direction of the sliding door main body, and a roller that moves the sliding door main body along the guide member by rolling by engaging with the guide member. It does not have to be done.
[0016]
Further, the sliding door body is provided with a plurality of rollers in the moving direction of the sliding door body, and provided with a roller that moves the sliding door body along the guide member by rolling by engaging with the guide member, One of these rollers and the guide member is formed to have a flange on both sides in the sliding door body thickness direction, and a groove having an arc cross section formed between these flanges, and the other is formed in this groove. When the engaging portion to be engaged is formed and the engaging portion is formed in a circular arc shape having a smaller radius of curvature than the groove, the position of the moving axis of the sliding door body guided by the guide member described above When the sliding door body receives the braking force of the braking device, the position of the braking axis of the braking device that applies a braking force to the sliding door body coincides or substantially coincides with the position of the sliding door body in the thickness direction. The engagement with the flange Preparative may be a sliding door body is not moved to the sliding door body thickness direction with respect to the guide member to contact.
[0017]
In this way, when the sliding door body moves while being guided by the guide member while receiving the braking force of the braking device, the flange and the engaging portion do not come into contact with each other, and generation of resistance force when this contact occurs is prevented. As a result, smooth and damped movement of the sliding door body can be realized.
[0018]
This can be achieved even when the flange and the groove are formed on the roller and the engaging portion is formed on the guide member, and vice versa.
[0019]
The sliding door device according to the present invention is a sliding door device including a sliding door main body, a guide member for guiding the movement of the sliding door main body, and a driving device for moving the sliding door main body, and is guided by the guide member. The position of the moving axis of the sliding door main body and the position of the driving axis of the driving device for moving the sliding door main body are the same or substantially the same position in the thickness direction of the sliding door main body. It is.
[0020]
According to this sliding door device, the position of the moving axis of the sliding door main body guided by the guide member and the position of the driving axis of the driving device for moving the sliding door main body are coincident or substantially coincident with each other in the thickness direction of the sliding door main body. Therefore, when the sliding door body is moved by this driving force, the force for moving the sliding door body in the thickness direction of the sliding door body perpendicular to the moving direction can be eliminated or reduced. It is possible to prevent a large frictional force that is a resistance force of the sliding door body from moving to the member, and to move the sliding door body with a driving force that is the same or substantially the same as the original driving force of the driving device. Therefore, the sliding door body can be moved smoothly.
[0021]

It may be a tension type drive device having force applying means, and is connected to one of the sliding door main body and the immovable member, or attached to the other, and the piston rod is inserted in a telescopic manner. It may be a cylinder type driving device having a cylinder body, and furthermore, a rack member attached to one of the sliding door body and the stationary member, a pinion disposed on the other and rotatably meshed with the rack member, A rack and pinion type driving device having a motor for rotating the pinion may be used, and a linear motor type that moves the sliding door body by a repulsive force of magnetic force It may be.
[0023]
When the drive device is a tension type drive device, the drive axis is a tension line of the string-like member when tensioned. When the driving device is a cylinder type driving device, the driving axis is a moving axis of a piston rod that moves relative to the cylinder body. Further, when the drive device is a rack and pinion type drive device, the drive axis is relative to the movement axis of the pinion that moves while rotating with respect to the stationary rack member, or the pinion that does not move only by rotating. It becomes the movement axis of the rack member that will move. When the drive device is a linear motor system, the drive axis is the central axis of the repulsive force of the magnetic force received by the sliding door body.

When the driving device of the sliding door device is the tension driving device, the end of the string-like member may be directly connected to one of the sliding door main body and the stationary member. Preferably, a pin extending in the thickness direction of the sliding door main body is provided on one of the two, and the end of the string-like member is connected to the pin, so that the string-like member is connected to the one via the pin.
[0025]
In this way, since the pin has a length extending in the thickness direction of the sliding door body, changing the connection point of the string-like member to the pin, or making the length of the pin itself variable, Alternatively, by changing to a pin having a different length, the connection position between the one and the string-like member can be adjusted in the thickness direction of the sliding door body. As a result, the driving axis when the sliding door body is moved by the driving device can be adjusted. The position can be set to a position that coincides or substantially coincides with the moving axis of the sliding door body in the thickness direction of the sliding door body.
[0026]
The sliding door device provided with the drive device of any type and structure described above applies a braking force to the sliding door body when the sliding door body approaches the closing limit position, when the sliding door body approaches the opening limit position, or both.

Further, in the sliding door device provided with the driving device, the sliding door main body includes a plurality of rollers arranged in the moving direction of the sliding door main body, and a roller that moves the sliding door main body along the guide member by rolling by engaging with the guide member. One of these rollers and the guide member has a flange on both sides in the sliding door body thickness direction and a groove having an arcuate cross section formed between these flanges. In the other case, an engaging portion that engages with this groove is formed, and when this engaging portion is formed in a circular arc shape having a smaller radius of curvature than the groove, it is guided by the guide member described above. The position of the moving axis of the sliding door main body and the position of the driving axis of the driving device that applies a driving force to the sliding door main body are the same or substantially the same in the thickness direction of the sliding door main body. The driving force of the drive unit is received. When the sliding door body to said flange and said engaging portion is in contact may be that it does not move the sliding door body in the thickness direction with respect to the guide member.
[0029]
In this case, when the sliding door body moves while being guided by the guide member by the driving force of the driving device, the flange and the engaging portion do not come into contact with each other, and generation of resistance force when this contact occurs can be prevented. The smooth movement of the sliding door body can be realized.

According to this sliding door device, the position of the braking axis of the braking device that applies a braking force to the sliding door main body and the position of the driving axis of the driving device that moves the sliding door main body match or substantially match in the thickness direction of the sliding door main body. Therefore, even if the braking force of the braking device acts on the sliding door body that is moving by the drive device, the sliding door body tries to move in the thickness direction of the sliding door body that is perpendicular to the moving direction. The force can be eliminated or reduced, and therefore, it is possible to prevent a large frictional force that is a resistance force of the sliding door body from moving with the guide member, and to smoothly move the sliding door body. become.
[0033]

[0037]
In this way, even if the sliding door body receives the braking force of the braking device while it is moving by the driving force of the driving device, the flange and the engaging portion do not come into contact with each other, and the resistance force is generated when this contact occurs. Therefore, smooth movement of the sliding door body can be realized.
[0038]
This can be achieved even when the flange and the groove are formed on the roller and the engaging portion is formed on the guide member, and vice versa.
[0039]

The piston rod 42 and the catch member 43 are connected in the same manner as described above by providing magnets with opposite magnetism in the tip portion of the piston rod 42 and the inside of the catch member 43 into which the tip portion is inserted. The connection can be freely separated.
[0063]
The cylinder body 41 is provided with a valve that sucks a large amount of air into the cylinder body 41 when the piston rod 42 is extended and discharges the air while the piston rod 42 is contracted. For this reason, the sliding door body 1 can be moved lightly during the opening movement of the sliding door body 1 in which the piston rod 42 is extended, and the sliding door body 1 is in the closed movement of the sliding door body 1 in which the piston rod 42 is contracted. It moves while being braked by the air pressure inside the cylinder body 41, and reaches the closing limit position at a reduced speed.
[0064]
For this reason, the braking device 40 in the present embodiment is a fluid pressure braking device using a cylinder device.
[0065]
Since the stop device 20, the drive device 30, and the braking device 40 described above are attached to the guide rail 10, these devices 20, 30, and 40 are guided in advance at a factory where each component of the sliding door device is produced. By attaching to the rail 10, the structure composed of the guide rail 10, the stop device 20, the drive device 30, and the braking device 40 can be transported to the construction site of the sliding door device as a unitized unit structure. Work on the construction site can be simplified that much.
[0066]
The operation of attaching the guide rail 10 that has become a part of the unit structure by attaching the stop device 20, the drive device 30, and the braking device 40 to the attachment member 11 of the upper frame 2 may be performed at the factory. Well, it may be done at the construction site of the sliding door device.

FIG. 8 is a schematic plan view of the sliding door device showing the position of the moving axis of the sliding door main body 1 by the guide rail 10 and the position of the driving axis of the driving device 30 for moving the sliding door main body 1 in relation to the thickness direction of the sliding door main body. It is.
[0068]
The sliding door body 1 moves while being guided by the guide rail 10 when the rollers 15 and 16 roll on the engaging portion 10 </ b> C of the guide rail 10, so that the moving axis A of the sliding door body 1 is related to the engagement of the guide rail 10. This coincides with the extending direction of the joint portion 10C. Further, since the sliding door main body 1 moves to the closing side by the tensile force acting on the string-like member 34 by the tensile force applying means 37 of the driving device 30, the sliding door main body 1 is moved to the closing side. The drive axis B is the same as the tension line of the string-like member 34. For this reason, the position of the drive axis B in the thickness direction of the sliding door body 1 is the same as the position of the string-like member 34 in the thickness direction of the sliding door body 1.
[0069]
In this embodiment, the moving axis A of the sliding door body 1 is at the center of the thickness dimension C of the sliding door body 1, while the driving axis B of the driving device 30 is Transfer It is at a position shifted from the movement axis A by the dimension D in the sliding door body thickness direction. However, since the displacement dimension D is small, the position of the movement axis A and the position of the drive axis B are substantially coincident with each other in the thickness direction of the sliding door body 1, and in this embodiment, the drive axis B is Since it is within the thickness dimension C of the sliding door body 1, the displacement dimension D is not more than half of the thickness dimension C of the sliding door body 1.
[0070]
When the sliding door body 1 moves to the closing side by a tensile force acting on the string-like member 34 of the driving device 30, a moment of a value obtained by multiplying the tensile force by the displacement dimension D acts on the sliding door body 1, and the sliding door is caused by this moment. A force for shifting the main body 1 in the thickness direction of the sliding door main body is generated, and a frictional resistance is generated between the rollers 15 and 16 and the engaging portion 10C of the guide rail 10, but the displacement dimension D is as described above. Therefore, the frictional resistance that hinders the smooth movement of the sliding door body 1 can be reduced, and the sliding door body 1 can be moved smoothly by the driving device 30.
[0071]
Further, since the pin 36 to which the end portion of the string-like member 34 on the sliding door body 1 side is coupled extends in the thickness direction of the sliding door body 1, the end portion of the string-like member 34 coupled to this pin 36. Can be changed to the center side in the thickness direction of the sliding door body 1, and by making this change, the frictional resistance that hinders smooth movement of the sliding door body 1 can be further reduced.
[0072]
FIG. 9 is an outline of the sliding door device showing the position of the moving axis of the sliding door main body 1 by the guide rail 10 and the position of the braking axis of the braking device 40 for braking the movement of the sliding door main body 1 in the sliding door thickness direction. It is a top view.
[0073]
The moving axis A of the sliding door body 1 coincides with the extending direction of the engaging portion 10C of the guide rail 10 as described above. When the sliding door body 1 moves to the closing side and this movement reaches a predetermined position, the catch member 44 provided on the sliding door body 1 comes into contact with the piston rod 42 of the braking device 40, and thereafter the piston rod Since the braking force of the braking device 40 with respect to the movement of the sliding door body 1 is generated by the contraction operation of the cylinder body 41 with respect to the cylinder body 41, the braking axis E of the braking device 40 coincides with the movement axis of the piston rod 42.
[0074]
As shown in FIG. 9, in this embodiment, the braking axis E of the braking device 40 is at the center of the thickness dimension C of the sliding door body 1, and accordingly, the moving axis A of the sliding door body 1 and the braking of the braking device 40. Axis E is a position that coincides in the sliding door body thickness direction. For this reason, the driving force of the driving device 30 does not act on the sliding door body 1 because the driving device 30 is not attached to the sliding door device, and the braking force of the braking device 40 is applied to the sliding door body 1 moving to the closing side. When this occurs, the braking force does not generate a force for moving the sliding door body 1 in the sliding door body thickness direction. Further, when the braking force of the braking device 40 acts on the sliding door main body 1 that is moving to the closing side by the driving force of the driving device 30, the position of the driving axis B of the driving device 30 and the braking axis E of the braking device 40. Is only shifted by a dimension D in the sliding door main body thickness direction, and these axes B and E are in positions substantially coincided with the sliding door main body thickness direction. A large frictional resistance that hinders smooth movement of the main body 1 does not occur between the engaging portion 10C of the guide rail 10 and the rollers 15 and 16, and the sliding door main body 1 responds to the braking force of the braking device 40. Move smoothly while maintaining deceleration speed.
[0075]

The rollers 15 and 16 are provided with flanges 15A and 16A on both sides of the sliding door main body in the thickness direction. Further, the surface 10F of the engaging portion 10C of the guide rail 10 has an arcuate cross section, and the curvature radius of the surface 10F is smaller than the curvature radius of the arcuate grooves 16C, 16C.
[0076]
The positional relationship between the moving axis A of the sliding door body 1 and the driving axis B of the driving device 30 in the thickness direction of the sliding door body described above, the positional relationship between the moving axis A of the sliding door body 1 and the braking axis E of the braking device 40, and driving When the positional relationship between the drive axis B of the device 30 and the brake axis E of the braking device 40 is determined, even if the sliding door body 1 moves in the sliding door body thickness direction with respect to the guide rail 10, the flanges of the rollers 15 and 16. 15A and 16A are determined so as not to contact the engaging portion 10C of the guide rail 10.
[0077]
In this way, the rollers 15 and 16 for guiding and moving the sliding door body 1 along the guide rail 10 receive the resistance force generated when the flanges 15A and 16A and the engaging portion 10C come into contact with the guide rail 10. The smooth movement of the sliding door body 1 can be ensured.
[0078]
Further, as shown in FIG. 4, the engagement center position F of the rollers 15 and 16 with respect to the guide rail 10 is matched or substantially matched with the gravity center position G of the sliding door body 1 in the sliding door body thickness direction.
[0079]
According to this, even if there is a large gap between the guide roller 17 and the channel member 1B at the lower end of the sliding door body 1, the sliding door body 1 can be suspended from the rollers 15 and 16 with a large inclination angle with respect to the direction of gravity. There is no. For this reason, it becomes possible to prevent the sliding door body 1 from moving while the flanges 15A and 16A of the rollers 15 and 16 and the engaging portion 10C of the guide rail 10 are in contact, and the sliding door body 1 can be smoothly moved. it can.
